Chapter 6. Editors

Ed-1.14.2

Introduction to Ed

Ed is a line-oriented text editor.
It is used to create, display, modify and otherwise manipulate text
files, both interactively and via shell scripts. Ed isn't something
which many people use. It's described here because it can be used
by the patch program if you encounter an ed-based patch file. This
happens rarely because diff-based patches are preferred these days.

This package is known to build and work properly using an LFS-8.2
platform.
